As previously mentioned, I have four cats. FOUR. To put it bluntly, that’s a lot of cat turds. Which in turn means that I go through kitty litter like it’s my job. So while a a free 14-day trial of Perfect Litter is awesome, it only last about five days in this house. But still, free is free, right? Plus Perfect Litter is one of those cool, innovative products that does more than just clump cat poop: It will actually test your cat’s urine & alert you to if your poor baby kitten has a urinary tract infaction - a surpisingly common & nasty problem for cat owners. The litter turns hot pink if your cat is afflicted, and you’ll know that a visit to the vet is in order. Furthermore, the stuff is flushable, dust-free and low-tracking, and has some powerful odor-killing properties. Pretty much everything you could ever ask for in a cat litter, right? You do have to pay $3.95 shipping, since kitty litter is pretty heavy… but them’s the breaks.
